T I I ATTORNEYS- matter that is drawn into patented Apr. 13, 1943 DUSTBAG ATTACHMENT FOR SUCTION CLEANERS Charles L. Moorhead, Lakewood, OhioApplication March 24, 1941, Serial No. 384,975 1 6 Claims.

The purpose of this invention has been to devise a novel type of dustbag supporting means for use in conjunction with so-called suction orvacuum cleaners, as commonly known today.

A primary object of the invention has been to design a special type ofholder for securing for the cleaner in position which are usuallyapplied thereto incident to the passage through the bag of the highpressure air which is laden with dust that it carries into the bag fordeposit in the latter, the holder being of such construction as not tointerfere in any way with the function of porosity of the bag in use.

By the provision 'of the novel holder of the invention it is possible,in the first place, to use for the bag material light cotton or someequivalent cheap material which permits of throwing away of the bagitself when it is filled with dust and no longer useful, thuseliminating the necessity of emptying the bag of the dust and using thebag again or for successive operations of cleaning. It is well knownthat the emptying of dust bags for cleaners is a'somewhat unpleasanttask because of the handling of the dirt or foreign the bag receptacle,due to the necessity of shaking the bag, and the fact that the dustparticles are distributed in the air breathed'by the person doing thework.

A primary object of the invention has been to design the holder abovementioned in the form of a skeleton or cage-like structure made ofinherently stiff material such as wire or metal parts of a similarnature, so that the holder when it is applied to the cleaning machine isself-sustaining by reason of its inherently stiff structure.

A further object of the invention has been to so design the bag holder,that it may be quickly clamped upon and removed from the machine, andthe operations of removal of the dirt filled bag and replacement of afresh bag are thus facilitated.

A further object of the invention has been to so design the bag holderthat when it is made in its preferred small size to receive bagreplacements. the structure oflers a basis for providing the user of themachine with replacement bags in quantities, thus offering themanufacturer an outlet for additional business with reference to thesupplying of the bags.

Still another object of the invention has been to use, in associationwith the bag holder, a container which, when niounted adjacent to thebag holder and; preferably supported thereon, will supply to the bag, ifdesired, drops of moisture tending to impregnate the bag walls andmaintain the latter in wet condition for facilitating the filtering ofthe dust from the air as the air passes through the bag to the outeratmosphere, the bag retaining the dust passing thereinto from thedischarge neck of the cleaner.

Other advantages of the invention will be appreciated upon referencetothe following full description of detail construction of the parts andthe illustration thereof in the accompanying drawing, in whic Figure 1is a side elevation of 'a suction or vacuum cleaner equipped with theinvention.

'In the drawing the vacuum cleaner illustrated is simply one type incombination with which the invention may be types of cleaners are in usetoday and by slight modification of the structure of the bag holder theinvention may be adapted for employment upon such various types ofmachines.

The cleaner illustrated is "of the usual type including the body I onwhich the motor is supported, the suction fan casing 2, the nozzle headand supporting wheels 5. Cleaners of this type are equipped with adischarge neck -6 of some type, that illustrated, in the drawing havingopposite coupling pins 1 for engagement with the bag connector that isusually found upon these machines and includes a collar or equivalentmember provided with bayonet slots to interengage the pins 1 byr'otative movement for establishing the connection.

According to my invention, I employ a con nector 8 which iscomposed of aring-like body 9 having an annular flange 8', the body portion employed.Various different consisting of a cage-like or skeleton frame 9 beingformed with the bayonet slots H) designed to interengage with the pins 1with which the discharge neck 6 is usually equipped. It is of course tobe understood that for some types 6 where the pins 1 and bayonet slotconnector is not employed, the body 9 of the connector of this inventionmay be a spring clamp ring or any equivalent type of structure that isadapted to be clampingly or otherwise applied to the discharge neck 6for attaching a cleaner bag thereto.

The connector 8 of my invention has a tubular extension projectingtherefrom, the interior of which communicates with the space surroundedby the body 9. The purpose of this part U will be apparent hereinafter.

The essential feature of my invention comprises the holder |2 sodesignated generally and made up of longitudinal members l3 andtransverse members M. The holder frame is comprised of two semi-circularsections as seen in Figures 2, 3, and 4, there being hinge members i5connecting certain of the longitudinal members |3 of the sections at thelower portion of the holder. At the inner end of the holder |2 thelongitudinal members l3 are curved inwardly as shown at l3, and thenextended in a direction parallel with the main portions of said membersto provide clamping portions l6. Thereafter these members l8 areextended outwardly to provide U-shaped clamping portions i1 theextremities of which are connected by semi-circular transverse parts l8.

The transverse members H of the holder are made in curved form and thusprovide a ringlike structure as respects the cooperating members of thetwo sections in which the holder is formed. Similar curved parts I9 areused for the clamping portions it of the holder and connect thelongitudinal portions together as clearly shown in Figure 1 and inFigure 2.

The U-shaped members I! and the clamping parts It are designed to engageover the flange of the connector 8 and the tubular extension ll of saidconnector, respectively. The purpose of these members l1 and l6 is toprovide a means for attachment of the cage-like holder |2 to theconnector 8, and in addition to this to clamp the inner portion of thebag 20 received in the holder l2 snugly around the part II and aroundthe flange 8 of the connector as seen best in Fi ure 2.

If desired, above the holder |2 may be disposed the liquid receptacle 2|which is capable of containing water or a chemical such as liquiddisinfectant, and this receptacle 2| is provided with perforations 22 inits bottom portion from which the liquid contained therein may drip ontothe bag 20 and thus ultimately wet the entire bag by distributing overits surface through capillary movement. The receptacle 2| may besupported in any suitable way, but is preferably carried on the upperportion of the holder |2 by means of spring clips 23 adapted to engageover the upper longitudinal members i3 of the holder. Thus, thecontainer 2| may be readily removed and replaced for purposes ofrefilling, a filling cap 24 being provided for such purpose.

With the foregoing construction of my invention presented, its operationwill be readily apparent. To emplace the bag 20 within the holder i2,the spring catch 25 is used which engages two of the U-members |1receiving the flange 8' of the connector in order to clamp the bagholder onto the connector. By disengaging the spring catch 25 the twosections of the holder i2 may be separated as by swinging one of thesections to the dotted line position shown in Figure 3. It will beassumed that previous to doing this the receptacle 2| has been removed,if it is used. It is understood, however, that my bag holder may beemployed either with or without the receptacle 2|, depending uponwhether the customer employing the cleaning machine wishes to avail ofthe moisture applying means 2|.

When the sections of the holder |2 have been operated after the mannerroughly illustrated in Figure 3, the receptacle 2| having beenpreviously removed, the bag 20 will be placed with its larger portionwithin the space to be surrounded by the sections of the holder l2 andadjacent to the por tion in the larger part of the holder. The bag willbe clamped around the tubular extension l of the connector 8. Also, theopen end portion of the bag will be clamped around the flange 8' bymeans of the U-meinbers H. The bag will thus be firmly attached to theconnector 8 in the manner seen in Figure 2 when the sections of the bagholder |2 are caused to move together and assume the positions in fulllines in Figures 1. 3, and 4.

The above operation will preferably be performed by removing theconnector 8 from the discharge member 6, this being conveniently done bysimply disengaging the part 9 from the pin 1 by slightly rotativemovement to remove the pins from the bayonet slots l0.

After the bag has been clamped in position inside the holder l2 andsnugly fitting about the parts II and 8', the spring catch 25. will beengaged to maintain the sections of the holder i2 closed around the bag.Upon starting the machine of course the bag 20 will be inflated as usualand air will pass through the pores thereof, the dust being retainedwithin the bag as customary.

The removal of the bag will involve merely the opposite of the operationabove indicated for the application of the bag to the holder i2 and themethod of removal is obvious. If the receptacle 2| is used it will bedetached first, preliminary to the separation of the sections of theholder |2, for bag removal purposes.

Obviously, by the use of the invention, as the bag is inflated, thewalls thereof will be caused to contact with the various longitudinaland end members of the body of the holder l2. Such contact will relievethe bag of the stresses and strains incident to the powerful blast ofair which is entering the same and which efi'ects its inflation. Thusthere may be used by means of the invention a lighter materal for thebag, one which is so cheap or inexpensive as to enable it to be readilythrown away when the bag is filled with dust, thus eliminating thenecessity for emptyingthe bag every time it is filled. Of course, if theperson using the cleaning machine prefers to empty the bag, he may doso, but when the bag holder I2 is made relatively small and adapted forsmall size bags 20 it will be seen that the more suitable operationwould be to simply throw away the bag 20 containing the dust aftercleaning operations sufficiently to fill the bag have been performed.

It will be apparent that when the receptacle 2| is used, the springclips 23 assist in holding the sections of the holder |2 together byclamping against the uppermost longitudinal members l3 of the holder.

Having thus described my in'vention, what I claim as new and desire tosecure by Letters Patent of the United States is:
